====Attention Deficit Hyperactivity Disorder====
[[ADHD]] is the condition most commonly associated with conduct disorders, with approximately 25–30% of boys and 50–55% of girls with conduct disorder having a comorbid ADHD diagnosis.<ref name="Waschbusch">{{cite journal | author = Waschbusch D.

'''Oppositional Defiant Disorder''' 

[[Oppositional defiant disorder|ODD]] is a mental disorder characterized by angry, argumentative, and resentful behavior. ODD and CD both fall under the umbrella of Disruptive Behavior Disorders (DBD). The main difference is in severity. While ODD is based on verbal hostility, CD is more severe in that it includes aggression and violence towards other people and animals, theft, deceit, and breaking of rules. <ref>{{Cite journal |last1=Kerekes |first1=Nóra |last2=Lundström |first2=Sebastian |last3=Chang |first3=Zheng |last4=Tajnia |first4=Armin |last5=Jern |first5=Patrick |last6=Lichtenstein |first6=Paul |last7=Nilsson |first7=Thomas |last8=Anckarsäter |first8=Henrik |date=2014-04-22 |title=Oppositional defiant- and conduct disorder-like problems: neurodevelopmental predictors and genetic background in boys and girls, in a nationwide twin study |journal=PeerJ |language=en |volume=2 |pages=e359 |doi=10.7717/peerj.359 |doi-access=free |issn=2167-8359 |pmc=4006222 |pmid=24795851}}</ref> ODD has also been found to be a precursor for CD.
